Abstract

Sistema de portero electrónico digital. Cuenta con al menos una pluralidad de teléfonos de vivienda (1), placas de calle (2) y módulos abrepuertas, al objeto de posibilitar la entrada a la vivienda por más de un acceso. Dispone de medios que permiten la conexión entre todos los diferentes elementos (teléfonos, placas, módulos) con cable de dos hilos carentes de polarización en lo que respecta a la conexión de los teléfonos de vivienda (1), posibilitándose con ello tanto comunicaciones analógicas de audio como comunicaciones digitales del sistema, y que cada borna de los referidos elementos acoja indistintamente a uno u otro de esos dos hilos. Los referidos medios proporcionan una señal digital que se transmite por los aludidos elementos, informándoles en todo momento del estado del sistema.
